Quinn added that much of the liability exposure stems from a shop using outdated or improper repair procedures.

 

“Technology also plays a role,” he said. “Modern ADAS systems, such as adaptive cruise control, lane keep, blind spot monitoring and other systems using cameras, sonar, radar and LIDAR sensors require calibration after replacement or repair.

 

“Even a minor collision can cause damage to these systems because they are not protected by ultra-high strength steel enclosures, but rather located right on the exterior of the vehicle.”

 

This is why a comprehensive estimating process now demands a pre-repair scan of the vehicle to identify any trouble codes and a post-repair scan to verify that these systems are all functioning properly, explained Quinn.

 

Quinn then shared a slide on what is included and not-included in pre-scans and post- scans.

 

“Scan” included operations:

 

• Locating the keys, vehicle and repair order


• Moving the vehicle to a designated area


• Running the vehicle long enough to reach operating temperature (note: antilock brake controllers can be temperature-sensitive)


• Locating and connecting battery support


• Locating and connecting scan tool


• Cycling the key


• Submit the scan request (which includes data entry of items like the vehicle and collision information)


• Reviewing the scan report

 

“Scan” not-included operations:

 

• Resetting and clearing stored faults


• Testing and diagnostics


• Liftgate / door relearns


• Adjusting passenger seat for seat weight sensor


• Test-driving the vehicle in accordance with the OEM’s repair procedures


• “Wiggle” test wiring harness to uncover short or ohm change on readings of live data


• Fuel level


• Check / adjust Tire Pressure


• Wheel speed sensors: through live data, voltage signal can be inspected - if faulty sensor is suspected shop may need to R&I wheel and inspect wheel sensors (common on suspension damage)


• Rear parking sensors: start vehicle and have a second person walk behind vehicle to ensure integrity of sensors


• ‘360 Camera’s: start vehicle and have a second person walk around vehicle to ensure integrity of sensors


• Initialization of modules


• Reprogramming of modules


• 4W Alignment BEFORE any steering angle sensor calibration or ADAS calibrations


• ADAS Calibrations


• Calibrations of radar


• Calibrations of sensors


• Calibrations of cameras


• Calibration of 360 camera systems


• Calibration of adaptive headlamps


• Calibration of seat weight sensor – SWS


• Calibration of forward-looking cameras
